To track direct mail response, give every campaign its own response path, such as a tracking phone number, QR code, promo code or unique web address, and then match those responses to actual sales. The response shows that people noticed your ad. The sales match shows whether it paid off.
Most businesses stop at the first step. In Uniqode’s State of QR Codes 2026 survey of US marketers, 56% expected QR codes to drive more revenue, but only 12% actually measure their revenue impact (Decision Marketing). The same gap shows up with calls, coupons and clicks. This guide covers the five ways to track response, which numbers Valpak reports and which ones live in your business, and how the two fit together.
Why one tracking method is never enough
People respond to the same mailer in different ways. One household calls the number on the coupon. Another scans the QR code at 10 p.m. and orders online. A third tucks the coupon in a drawer and brings it to the counter two weeks later. If you only count calls, the second and third customers look like the campaign never reached them.
The strongest campaigns use the response paths that fit the business and add them up, so you see the whole response instead of the slice one channel can measure.
Count the responses, then read the details
Quantity is the count: 37 calls, 214 scans, 77 redemptions. It tells you whether the campaign is working. Quality is the detail behind each response: which day, which device, which neighborhood and, for calls, what happened on the line. That’s what tells you what to do next.
Forty scans can sound modest on its own. Forty scans clustered in the three days after the mailer landed, mostly from phones in a handful of ZIP codes, is a picture of a campaign working in a specific place at a specific time. It’s also a strong hint about where to mail next.
Valpak attribution tracking measures both the quantity and quality of the responses your campaign generates. Calls, scans and redemptions are reported in Advisor, your campaign dashboard, so your results are a report you can review yourself, not an estimate built after the fact.
1. Call tracking: who picked up the phone
Your ad features a unique tracking number that rings straight through to your regular business line. Callers don’t notice anything unusual. Behind the scenes, each call’s date, time and details are logged in Advisor, where you can also listen to call recordings. Some industries, such as medical practices, may have limits on recordings and call details.
Calls are the strongest evidence a campaign can produce, because each one is a person with a need deciding to talk to you. In Invoca’s analysis of 70 million calls, 42% of qualified phone leads bought or booked before hanging up (Invoca, 2026). That intent is why home services campaigns are typically built around call tracking.
Expect some callers to dial your main number instead, especially repeat customers and people who look you up rather than reading the number off the ad. Those calls won’t appear in your tracking report, but they’re still results the campaign influenced. Asking “How did you hear about us?” helps you capture them.

2. QR codes: who wanted to know more
QR codes are no longer a novelty. Uniqode’s 2026 consumer survey found 71% of US consumers say QR codes are useful in daily life, and the top reason people scan is to get more information, at 75%, ahead of discounts at 52% (Uniqode State of QR Codes 2026). So a scan should land on a page that answers the question your ad raised, such as a menu, price list, booking page or the offer itself.
For trackable codes, Advisor reports every scan by date, device and geography. That detail is where QR codes earn their keep. A scan count tells you how many. The pattern tells you when, where and on what device people engaged.
3 rules of QR codes in advertising
- Use a dynamic code. It counts scans and lets you change the destination after the piece prints.
- Make it feel safe. Put your logo or brand colors near the code and print a short, readable web address beside it. In Uniqode’s research, 55% of consumers said a trusted environment makes them more likely to scan (CustomerThink).
- Tell people what they get. “Scan to see this week’s specials” gives people a reason to raise their phone. A bare code doesn’t.
3. Promo codes and redemptions: who bought
A redemption is the closest thing direct mail has to a receipt. For offers redeemed at your register or online checkout, a unique promo code does the same job. Use a different code for each mailing, offer or zone (for example, FALL-PIZZA-CLEARWATER) so you can compare them later.
Codes only work if they’re recorded. Train your front counter to enter every code, and accept that some customers will redeem the offer without one. Treat code counts as a floor, not a ceiling.
4. Web tracking: who went online
Many mail recipients skip the QR code and type your name into a search bar. Capture what you can with a short, unique web address printed on the piece that points to a dedicated landing page tagged with UTM parameters, which Google Analytics uses to label traffic by source. Then watch the halo: compare direct visits and branded searches in the weeks your mail is in homes against the weeks it isn’t.
5. Sales: what it was worth
Calls, scans, codes and clicks are signals. Sales are the result. To connect them, compare the addresses or ZIP codes of new customers during the campaign window against the areas you mailed. This is called a matchback, and it catches the customer who saw the mailer, never called or scanned, and walked in anyway.
With sales in hand, the math is simple:
- Response rate = total responses ÷ pieces mailed
- Cost per response = campaign cost ÷ total responses
- Cost per customer = campaign cost ÷ new customers
- Return on ad spend = campaign revenue ÷ campaign cost

What Valpak tracks and what your business tracks
No single company sees every step of the customer journey. Valpak tracks the first response to your ad. Everything that happens after that response reaches your business is yours to see. Put the two together and you get the full picture.
| What Valpak tracks | What your business tracks |
| Calls to the tracking number in your ad: date, time, call details and recordings | Which calls became leads, appointments and jobs |
| Scans of trackable QR codes by date, device and geography | What scanners did next on your site: forms, orders, bookings |
| Redemptions of your Valpak offer | Promo code use at your register or checkout, revenue and average ticket |
| All of it reported in your Advisor dashboard | Calls to your main line and walk-ins (“How did you hear about us?”) |
| New vs. returning customers, customer ZIP codes and lifetime value |
From first response to lifetime customer
Tracked response → Lead → Appointment → New customer → Lifetime value
Valpak reports the first link in that chain. The rest lives in your business: your phone notes, booking calendar, register and customer records. Your Valpak rep can only see what you share, and sharing even rough numbers turns a response report into an ROI conversation.
Not every campaign moves through all five stages. For a pizza coupon, the redemption is the sale. For an HVAC company, a call becomes an estimate, the estimate becomes a job weeks later, and a good experience becomes years of maintenance visits. Knowing which chain your business runs on tells you which numbers matter most.
How we work together on your campaign’s success
Before the first drop. Your Valpak representative works with you to set the goal (calls, bookings, foot traffic or online orders) and choose the response paths that fit it. Decide now how your team will record promo codes and log “How did you hear about us?”
While the campaign runs. Check Advisor as results come in. Listen to a few calls and look at when and where people are responding. Small fixes in week one, like a missed-call pattern or an untrained new hire, pay off for the whole campaign.
After each drop. Review the Advisor results with your rep and bring the numbers only you have: appointments, new customers, revenue and the ZIP codes they came from. Together, that shows which offers, areas and channels earned a place in the next campaign.
The businesses that get the most from direct mail treat tracking as a shared job. Valpak brings the response data. You bring the sales data. Together, they turn “I think it worked” into numbers you can plan around.

Direct Mail Tracking FAQ
How do you track direct mail response?
Give each mailer, offer or area its own response path, such as a call tracking number, QR code, promo code or unique web address. Count responses from each path, then compare new customers and sales during the campaign against the areas you mailed to see which responses turned into revenue.
What does Valpak track for advertisers?
Valpak attribution tracking reports calls to the tracking number in your ad (with call details and recordings), scans of trackable QR codes (by date, device and geography) and redemptions in the Advisor dashboard. Your business tracks what happens next: leads, appointments, sales and revenue.
Will my customers see a different phone number?
Yes. The tracking number appears in your ad and rings straight through to your regular business line, so callers won’t notice anything unusual. In exchange, you know exactly which calls came from the campaign.
What if customers call my main number instead?
Some will, especially repeat customers and people who look you up. Those calls won’t appear in your tracking report, but they’re still results the campaign influenced. Ask callers how they heard about you to capture them.
Can I listen to my call recordings?
Yes. Call recordings and call details are available in Advisor. Some industries, such as medical practices, may have limits on what can be recorded or shown.
Do QR codes work on direct mail?
Yes. In Uniqode’s 2026 survey, 71% of US consumers said QR codes are useful in daily life. QR codes perform best on mail when they’re trackable, branded, paired with a clear reason to scan and linked to a page that delivers what the ad promised.
What is a good direct mail response rate?
It depends on your industry, offer and audience, so the best benchmark is your own past campaigns. Track response rate alongside cost per customer and return on ad spend, since a lower response rate with higher-value customers can still be the better campaign.
